A nalog Frequency Multiplier P L560-xx VCXO Family P RODUCT DESCRIPTION P haseLink’s Analog Frequency Multiplier TM ( AFM) is the industry’s first ‘Balanced Oscillator’ utilizing analog multiplication of the fundamental frequency (at double or quadruple frequency), combined with an attenuation of the fundamental of the reference crystal, without the use of a phase-locked loop (PLL), in CMOS technology. PhaseLink’s patent pending PL560-xx family of AFM products can achieve up to 800 MHz output frequency with little jitter or phase noise deterioration. In addition, the low frequency input crystal requirement makes the AFMs the most affordable high-performance timing-source in the market. PL560-xx family of products utilize low-power CMOS technology and are housed in G REEN / R oHS compliant 1 6-pin TSSOP, and 16-pin 3x3 QFN packages.

Parasitic effects reduce frequency pulling of the VCXO and increase jitter.

The listed values in this datasheet are based on the calculated parasitic values from PhaseLink’s evaluation board design. These inductor values provide the user with a starting point to determine the optimum inductor values. Additional fine-tuning may be required to determine the optimal solution. To assist with the inductor value optimization, PhaseLink has developed the “AFM Tuning Assistant” software. You can download this software from PhaseLink’s web site (www.phaselink.com). The software consists of two worksheets. The first worksheet (named L2) is used to fine-tune the ‘L2’ inductor value, and the second worksheet (named L4) is used for fine tuning of the ‘L4’ (used in 4x AFMs only) inductor value. For those designs using PhaseLink’s recommended board layout, you can use the “AFM Tuning Assistant” to determine the optimum values for the required inductors. This software is developed based on the parasitic information from PhaseLink’s board layout and can be used to determine the required inductor and parallel capacitor (see LWB1 and Cstray parameters) values. For those employing a different board layout in their design, we recommend to use the parasitic information of their board layout to calculate the optimized inductor values. Please use the following fine tuning procedure: 4 7745 Fremont Blvd., Fremont, CA 94538 TEL (510) 492-0990, FAX (510) 492-0991 w ww.phaselink.com R ev.:02-09-07 Page 5 A nalog Frequency Multiplier P L560-xx V CXO Family F igure 5: Diagram Representation of the Related System Inductance and Capacitance D IE SIDE - C internal = Based on AFM device - Cpad = 2.0 pF, Bond pad and its ESD circuitry - C11 = 0.4 pF, The following amplifier stage PCB side - LWB1 = 2 nH, (2 places), Stray inductance - Cstray = 1.0 pF, Stray capacitance - L2X (L4X) = 2x or 4x inductor - C2X (C4X) = range (0.1 to 2.7 pF), Fine tune inductor if used • T here are two default variables that normally will not need to be modified. These are Cpad, and C11 and are found in cells B22 and B27 of ‘AFM Tuning Assistant’, respectively. • L WB1 is the combined stray inductance in the layout. The DIE wire bond is ~ 0.6 nH and in the case of a leaded part an additional 1.0 nH is added. Your layout inductance must be added to these. There are 2 of these and they are assumed to be approximately symmetrical so you only need to enter this inductance once in cell B23. • E nter the stray parasitic capacitance into cell B26. An additional 0.5 pF must be added to this value if a leaded part is used. • E nter the appropriate value for Cinternal into B21 based on the device used (see column D). Use the ‘AFM Tuning Assistant’ software to calculate L2X (and C2X if used) for your resonance frequency. • F or 4X AFMs, repeat the same procedure in the L4X worksheet. • S ee the examples in the following section. 4 7745 Fremont Blvd., Fremont, CA 94538 TEL (510) 492-0990, FAX (510) 492-0991 w ww.phaselink.com R ev.:02-09-07 Page 6 A nalog Frequency Multiplier P L560-xx V CXO Family D ETERMINING STRAY L’s AND C’s IN A LAYOUT F igure 6: Diagram Representation of the Board Layout L ets take the PL560-38 (4x VCXO) for example. This takes a crystal input in the range of 30 to 80 MHz and multiplies it to an output of 120 to 320 MHz. To determine the stray L’s and C’s of the layout we will assemble two test units. One AFM will be tuned to the lower range of the device (120 MHz), and the other to the upper range of the device (320 MHz). 1 20 MHz AFM Tuning: U sing the “AFM Tuning Assistant” find the PL560-3x in the L2X worksheet. Enter the Cinternal value found next to it into cell B21. In cell B24 enter the closest standard inductor value (see CoilCraft 0603CS series for example) to achieve the closest peak frequency to 60 MHz. Repeat the same procedure for L4X at 120 MHz. R esults: L2X = 180 nH, L4X = 82 nH . 3 20 MHz AFM tuning: R epeat the previous procedure for L2X at 120 MHz and L4X at 320 MHz. R esults: L2X = 24 nH, L4X = 10 nH . Proceed and assemble the test units. M easuring 120 MHz L2X: C onnect the RF generator and scope probe as shown in Figure 6, above. While power is applied to the PCB, set the generator output to +12 dBm and the frequency to 30 MHz. Since this is the 2x port, the scope will show 60 MHz with ~ 3V pk-pk amplitude. Vary the generator above and below 30 MHz until 4 7745 Fremont Blvd., Fremont, CA 94538 TEL (510) 492-0990, FAX (510) 492-0991 w ww.phaselink.com R ev.:02-09-07 Page 7 A nalog Frequency Multiplier P L560-xx V CXO Family t he amplitude on the scope is maximum and record the generator frequency. For example, the peak is recorded at 29.8x2 or 59.6 MHz. M easuring 320 MHz L2X: C onnect the RF generator and scope probe as shown in Figure 6, above. While power is applied to the PCB, set the generator output to +12 dBm and the frequency to 80 MHz. Since this is the 2x port the scope will show 160 MHz with ~ 3V pk-pk amplitude. Vary the generator above and below 80 MHz until the amplitude on the scope is maximum and record the generator frequency. For example, the peak is recorded at 78.0 x 2 = 156 MHz In the AFM Tuning Assistant, add the scope’s probe capacitance to the Cstray cell. For our example 0.5 pF + 1.0 pF = 1.5 pF. With L2X at 24 nH adjust LWB1 (cell B23) until the peak frequency reads 156 MHz. Next replace the L2X value with 180 nH and see if it peaks at 59.6 MHz. If it does not, adjust Cstray until 59.4 MHz is achieved. Again enter 24 nH for L2X and fine tune LWB1 for 156 MHz. R esults: LWB1 = 1.6 nH, Cstray = 2.9 pF-0.5 pF = 2.4 pF (subtract scope probe stray capacitance) R epeat the same steps for the L4X: Set the generator to 80 MHz. The 82 nH peaks at 118 MHz and the 10 nH peaks at 304 MHz. R esults: LWB1 = 1.8 nH, Cstray = 2.5 pF-0.5 pF = 2.0 pF (subtract scope probe stray capacitance) Internal Capacitor Selection by Device D evice Number 2X P560-0x P560-3x P560-4x P560-6x 7.625 34.125 34.125 7.625 Cinternal (pF) 4X 6.250 16.500 4 7745 Fremont Blvd., Fremont, CA 94538 TEL (510) 492-0990, FAX (510) 492-0991 w ww.phaselink.com R ev.:02-09-07 Page 8 A nalog Frequency Multiplier P L560-xx V CXO Family E LECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS P ARAMETERS S upply Voltage I nput Voltage, DC O utput Voltage, DC S torage Temperature A mbient Operating Temperature, Industrial Temperature A mbient Operating Temperature, Commercial Temperature J unction Temperature L ead Temperature (soldering, 10s) I nput Static Discharge Voltage Protection SYMBOL V DD VI VO TS T A_I T A_C TJ MIN.

Also be sure to bypass each Vdd connection especially taking care to place a 0.01 uF bypass at the Vdd side of L2X and L4X (see recommended layout). C rystal connections: B e sure to keep the ground plane under the crystal connections continuous so that the stray capacitance is consistent on both crystal connections. Also be sure to keep the crystal connections symmetrical with respect to one another and the crystal connection pins of the IC. If you chose to use a series capacitance and or inductor to fine tune the crystal frequency be sure to put symmetrical pads for this cap on both crystal pins (see Cadj in recommended layout), even if one of the capacitors will be a 0.01 uF and the other is used to tune the frequency. To further maintain a symmetrical balance on a crystal that may have more internal Cstray on one pin or the other, place capacitor pads (Cbal) on each crystal lead to ground (see recommended layout). R3rd is only required if a 3 rd o vertone crystal is used. V DD a nd GND: B ypass VDDANA and VDDBUF with separate bypass capacitors and if a V DD p lane is used, feed each bypass cap with its own via. Be sure to connect any ground pin including the bypass caps with short via connections to the ground plane. O ESEL: J 1 is recommended so the same PCB layout can be used for both OESEL settings. 2 X Layout (TSSOP) 4X Layout (TSSOP) 4 7745 Fremont Blvd., Fremont, CA 94538 TEL (510) 492-0990, FAX (510) 492-0991 w ww.phaselink.com R ev.:02-09-07 Page 12 A nalog Frequency Multiplier P L560-xx V CXO Family P ACKAGE PIN DESCRIPTION AND ASSIGNMENT GNDBUF VDDBUF QBAR Q OSCOFFSEL GNDOSC 1 2 16 15 L2X VDDOSC OESEL VDDANA VDDBUF QBAR Q GNDBUF VDDANA OESEL VDDOSC L2X 13 14 15 16 OSCOFFSEL GNDOSC VCON XIN XOUT OE DNC GNDANA 1 2 16 15 L2X VDDOSC 12 11 10 9 8 7 6 5 GNDBUF VDDBUF QBAR Q VDDANA 14 13 12 11 10 9 OESEL 12 13 14 15 16 11 10 9 8 7 6 5 GNDANA DNC OE VDDOSC L4X OE XOUT PLL560-0X PLL560-4X 3 4 5 6 7 8 VCON XIN XOUT 3 4 5 6 7 8 14 13 12 11 10 9 OESEL VDDANA VDDBUF QBAR P560-4X 1 2 3 4 P560-0X 1 2 3 4 VDDOSC L2X XOUT OE L4X VDDOSC OSCOFF SEL GNDOSC OSCOFF SEL GNDOSC Q GNDBUF 2 X AFM Package Pin Out VCON XIN 4 X AFM Package Pin Out P IN ASSIGNMENTS Name OSCOFFSEL GNDOSC VCON XIN XOUT OE DNC L4X 7 I Pin# 1 2 3 4 5 6 Type I P I I O I Product 2X & 4X 2X & 4X 2X & 4X 2X & 4X 2X & 4X 2X & 4X 2X 4X Description Set to “0” (GND) to choose to turn off the oscillator when outputs are disabled (OE).
